A mass is connected by a light string that passes over a pulley of mass M to a mass as shown in the figure. Both masses move vertically and there is no slippage between the string and the pulley. The pulley has a radius of 30.0 cm and a moment of inertia of If is 4.00 kg, is 3.00 kg and M is 6.00 kg, then what is the tension in the string that is attached to
